Question

Temperature change affects the rate of a chemical reaction by changing the __________ of the colliding particle.

A) charge
B) concentration
C) size
D) speed

Answer 1

D

Step-by-step explanation:

Speed

Answer 2

D) speed

Step-by-step explanation:

Reaction rates can be affected by several factors, including concentration, temperature, surface area and presence of a catalyst. Increasing concentration increases the number of effective collisions. Increasing temperature increases the kinetic energy of the particles, leading to more effective collisions
